THE TREATMENT REGISTRY

Verification tiers

Every clinic in the registry carries one of five tiers. Tier reflects what we have independently confirmed; it does not measure clinical quality. The flag attribute is orthogonal: a Tier 2 clinic can be flagged, and a Tier 1 clinic can have an open flag against it.

Tier 1 — highest

All four of:

  • International accreditation confirmed against the issuing body’s public directory.
  • National regulator confirmed (clinic appears on the relevant medical, dental, or facility licence register).
  • Corporate registry confirmed (entity active, registration number on file, registry URL on file).
  • At least one independent third-party data point — peer-reviewed publication, listed-hospital filing, or registry outcome data.

Tier 2

All three of:

  • National regulator confirmed.
  • Corporate registry confirmed.
  • At least one accreditation either confirmed against an issuer’s register or self-declared with a documented certificate URL.

Tier 3 — lowest verified

Corporate registry confirmed only. The clinic exists as a registered legal entity. Accreditation and credential claims have not been independently confirmed.

Listed

The clinic appears in the directory because it has been mentioned in patient reports, search queries, or facilitator listings, but the registry has not yet checked anything against primary sources. Treat as unverified pending review.

Withdrawn

Previously listed; no longer trades or has been removed at the clinic’s request after a documented review. The record is preserved for the corrections log.

Flag — orthogonal

A flag is a documented, sourced concern about a specific factual claim — for example, an accreditation that cannot be verified, a dissolved corporate entity, or a documented review-manipulation pattern. Flags are independent of tier. A clinic can move between tiers without affecting an open flag, and a flag can be raised or resolved without changing the tier. See flag criteria.
